On my car. I activated the throttle from the engine compartment and could feel it engage, but when I let off the throttle, it would disengage. Even if I held the rpm's up, the fan would disengage.

If you are talking about the "vfc" then it operates when the bimetallic strip (bms) gets enough bend to activate the 'pin' clutch that release the silicone gel into a chamber that locks in the fan. Read Menu#20 for more info on how it operates.
It disengages with high rpm, around 2500rpm on the tach independent of temp. It does that b/c the fan is not needed due to the high road speed which forces air into the rad and engine.
Re 'leaking hoses'; if that was the problem you should have seen some coolant on the ground or on the garage floor by now.
